Twin compressors, Autopilot V2 wiring

[MeanTC]

This is exactly what I recommend as well. These are high current relays and will run 2 comp systems no problem. The highest current draw you will have is when the compressors cycle on.

If your running 1 power wire for an amp and dual compressors you want 80A at lowest but 100A preferred. Then use a distribution block to run multiple power sources off that one.

From the High amp relay (like Stinger relay) you can run both compressor wires to the switch side (87) of the relay.

That is my setup 100A on main line then to the Y from there one to amp and then the other one to an 80A then to stinger then to pumps. no probs at all.

Used to have the same problem just get this http://www.sonicelectronix.com/item_...ger-SGP38.html all the bag truckers run them here. I do to and have no problem. just run it off you amp power wire and you just use one large fuse those little relays are trash ask any mimi trucker whos been doing it for years they also use starter relays too.

I have a 0 gauge power wire with a Y connection one to the amp and one to the stinger with of course an 80 amp fuse before the stinger.

thats why I always keep spare fuses in the glove box

to the op what did you have questions concerning welding and fittings?

Wow, you must have been a boyscout or something. How about if the wiring takes a dump and you burn through your spare fuse. Running dual fuses cuts one full circuit out of the failure modes and effects analysis, so it's much more robust.

I did one fuse.... should redo it to have two. Can't believe I didn't think of the fuse burning out and leaving me stranded

i do it like in the second diagram posted but with 2 inline fuses.

So many fucking earths !

Right. I'll go and look in the morning. If worst comes to worst. I can just hook one up now.

What do you recommend

Also. Any tips for welding / fitting please? Run wiring and front airlines already

do the diagram you posted, i've done it like that for years with no issue. I like using two separate in line fuses though so if the one big fuse goes out, you arent fucked.

yea, it will work perfectly fine. I just dont like using positive triggers when there is a negative option. I would wire up the second relay exactly like the first and diode isolate the trigger from the manifold. IMO there is no need for a 30a pos trigger. that just seems absurd to me lol

yep. it makes sense as in its not confusing but i wouldnt do it like that either. the first diagram has the second relay relying on the first. so if the first relay goes bad, both compressors are out. lol.

[Jorge]

Okay. See what I can do. Thanks!

the first diagram makes perfect sense. when one compressor is powered, you tap that power line that goes to the compressor and run it through the other relay trigger to ground. then that closes the bridge to feed power to the second compressor.
